A lens that can see behind itself – the idea is almost boggles the mind, but this is what the Fisheye-Nikkor 6mm f2.8s that claims to do, to provide 220-degree viewing angle. This giant of a fisheye lens was introduced in 1972, and reportedly only available by special order. Price to get your hands on one now? Oh, only about £ 100,000 ($ 161,210 U.S.) for the lens in mint condition, and only from Grays of Westminster, London camera shop that deals exclusively with Nikon products. This is not the first time that this wonderful piece of glass appeared, two years ago a similar lens eBay $ 34,020 hit songs – really cheap, in comparison. See the source link below to look at the sales. Wallet can not take damage? Range “scope” for a little history of Nikon.
O patent application … where the creative idea of dance shoulder to shoulder with ill-conceived folly. Which we have here now? We’re not sure. What we are sure, however, is that someone in Microsoft has already filed a patent application describes a device with two screens. Not brown, but the second screen of the lower-power, such as e-ink, and show different information based on the initial state (ie whether or not in your face.) Not-to-be- believed to describe the second image screen covering the back of the device and shows the time, or other user defined information. This application does not state that will continue to show the information, even if the device is in sleep mode, and describes the contours are not flat. If you read it, may sound like the behind the e-ink phone housing, but if it ever comes to pass, perhaps a little dressing down, so do not be too pleased.
